Welcome to the 'what game were you watching' player ratings. Today, the game we were watching was one which ended with Ireland being crowned Grand Slam champions for only the third time in the history of the competition.
You will not be surprised to learn that the ratings are a celebratory affair on this afternoon.
And fair warning to those who've recently sworn an oath never to give Rob Kearney credit for anything ever again - he does get marked highly.
No apologies will be made for that.
15. Rob Kearney 9
Spoke beforehand about how he'd gone into his shell for Ireland's last grand slam victory in 2009. He discarded the shell before action commenced today.
In the first few minutes, he unsettled Anthony Watson enough in the air to allow Garry Ringrose to touch down for the opening try.
It teed him up for an exemplary performance at full-back.
Superb in the air, he beat more defenders throughout the 80 minutes than any other player on the pitch. His decision making as regards when to run and when to kick was flawless.
14. Keith Earls 8
Did so much right defensively, from his Stringer-esque ankle tap on Elliot Daly early in the second half to touching down in front of the winger to prevent a score at 5-24.
Was fended off rather easily by Mike Brown for Daly's second score but otherwise a smashing effort from a player who has hit the form of his career in his early thirties.
He only properly announced himself as a wing in 2009 and arrived just too late for that year's Slam success. Fortunately, he played a starring role in 2018.
13. Garry Ringrose 8.5
Alertness and game intelligence personified.
Did brilliantly to nip in for the opening try and shortly afterwards stripped a ball from the hands of Richard Wigglesworth only five metres from the Irish line.
Ireland have a multitude of options at centre - or at least they did before they all wound up on the treatment table - but Ringrose stands out as the most talented.
12. Bundee Aki 7
Dropped a ball with the try line in sight at 0-7 but redeemed himself shortly after laying on the second try for CJ Stander with an inside pass.
A fearsome presence in defence as usual, he was perhaps lucky to avoid a sin-binning after bashing into Elliot Daly as England pushed hard for a first half try.
11. Jacob Stockdale 8
Spectacular finishing and now a Six Nations record-breaker. No player had ever managed seven tries in a single campaign until today.
Saw hardly any ball in the first half and only really got his first sniff of a chance on the stroke of the break. But as he's made plain in this campaign, all he needs is a sniff.
Eddie Jones said afterwards that England wanted to play with bigger in-goal areas today and had them extended to the max this afternoon. The only person to benefit was Stockdale.
Chased kicks to great effect all afternoon and bull-dozed through Mike Brown at one point in the second half. Always a pleasing sight.
10. Jonathan Sexton 7
A quieter afternoon and one interrupted by injuries and HIA protocols. He missed his only shot at a penalty in the opening half and Conor Murray would take over those duties early in the second half.
Was probably injured a while before he was taken off after being hit by Ben Te'o. It won't matter that he was more subdued that usual. He has that Grand Slam that he richly deserves.
9. Conor Murray 9
"Murray, Murray, Murray!" was the anxious cry of the England forwards at ruck time all afternoon. The reputation of Ireland's No. 9 precedes him and he strikes panic into opposing teams.
Box-kicking and game management were perfect as usual. The best scrum half in the world and Ireland's greatest ever scrum half.
Stepped up to slot Ireland's only three-pointer of the afternoon early in the second half.
1. Cian Healy 8
An excellent day in the scrum for Healy and a trojan defensive effort. Not the flashiest or the most striking of the Irish forwards in the loose but a fine day's work for the loose head.
2. Rory Best 8
Threw well as the Irish lineout recovered from its wobble against Scotland.
Their set-piece was back on song on Grand Slam Saturday as Best found his target with all 12 of his darts. Like every other member of the pack, Best's workrate was exemplary.
The 35 year old was confined to cameo roles in each of the games when Ireland claimed the grand slam nine years ago.
Not so in 2018 as he ended the tournament by hoisting the Six Nations trophy aloft in the home of English rugby.
3. Tadhg Furlong 9
It's rather rare for a prop to be awarded Man of the Match. It's even rarer for a prop to pop a pass to Aki of the type which Furlong in the first half.
The stats only confirm the impression that Furlong had a game for the ages. He made a total of 14 tackles without missing a single one.
As one would expect, his scrummaging was supreme all day. The best tight head in the world.
4. James Ryan 8
What a debut season. His defensive efforts when Ireland were under pressure in the second quarter marked him out. He executed 13 tackles without missing a single one.
5. Iain Henderson 8
This is getting monotonous now. Another worthy foot-soldier in a famous effort by the Irish pack. Made 15 tackles over the course of the eighty and was a key part of a superb Irish lineout display.
6. Peter O'Mahony 7
In a fraught second quarter when Ireland were scrapping and tearing to prevent England getting on the scoreboard for as long as possible, there were a few Irish players who could have been sin-binned, namely, Iain Henderson, Bundee Aki (very lucky) and Peter O'Mahony.
It was the latter who got the bin. Otherwise, he was his usual aggressive and snarling presence at the breakdown and contributed handsomely to Ireland's unsurprising supremacy in that department.
7. Dan Leavy 9
Another sensational performance from the flanker who has truly written his name in lights in this campaign.
Again, his mastery of the breakdown was on display and he made more tackles than any other Irish player on the afternoon.
And he proved a useful option in the lineout as the Irish throw bounced back from last week's messy display.
8. CJ Stander 8.5
Made more metres than any other forward on the pitch. Completely standard at this stage. He made a whopping 22 carries across the 80 minutes.
His game was decorated by his first half try, brilliantly finished as he touched down at the goalpost.
Replacements:
Joey Carbery 8
Missed his sole kick at goal but it was a long distance one but even the most pessimistic of Irish fans would have concluded that Ireland had things in hand at that stage.
Should by rights have been nervous on replacing Johnny Sexton late in the first half and midway through the second half.
But he hardly put a foot wrong in general play and he looked a jinking and dangerous presence with the ball in hand.
Sean Cronin 8
Smashing little cameo from the Leinster hooker who did terrifically to put Mike Brown in touch and England were desperately scrambling to manufacture a try in the closing stages.
Jordan Larmour 8
In the Six Nations to date, he's only had time to showcase the odd defensive lapse. Today's cameo was more to his liking and he made one memorable darting run which carried him to within metres of the line as Ireland chased a fourth try.
Jack McGrath 7.5
Made eight tackles and missed one during his brief period on the pitch.
Andrew Porter 7
Not on for long but mustered five tackles and embarked on one bullocking run at the heart of the England defence. Was an unknown quantity for many supporters at the beginning of this season.
Devin Toner 7
Came on late in the game and made some tackles and missed a couple of tackles. It should be remembered that Ireland were under sustained pressure during his time on the pitch.
Won his third Six Nations title this year. Superb stuff.
Kieran Marmion 7
Came on at wing as Keith Earls hobbled off. Not the first time he's had to fill in there. Got his hands on the ball but not long enough on to be rated in truth.
Jordi Murphy 7
Probably not on long enough to be rated so we will grant him the Brian Glanville median rating of 7.
Was a more prominent figure in Ireland's 2015 Six Nations triumph but this spring he did make appearances against both Scotland and England.
